Allen The South's Common Green Tree Frog Poses as Hunter, Philosopher, and Troubadour A Candid Shot Catches the Seldom-seen Bird-voiced Tree Frog (Lower Left) Like a face at the window, Green Tree Frog (Hyla cinerea) prowls a pane in upper left hunting for insects attracted by the light. Big toe and finger suction pads. common to all tree frogs, give him sure footing. Resting by day (upper right), he takes the world as it comes. Turned golden, at night, he sits on a lily pad serenading his ladvlove with cowbell-like notes. His call is one of the South's most characteristic Nature sounds. A single Bird voiced Tree Frog (Hyla avivoca) sounds like a distant pileated woodpecker. A chorus ebbs and flows in great waves, confusing the listener as to identity and location. Living chiefly in tupelo and cypress swamps from Georgia to Louisiana, avivoca is hard to find.
